2012-08-12 – EEG Blinks

Rapid Eye Movements Electroencephalograph
After a few nights of recording brainwaves from the NeuroSky MindWave and some advice from a cognitive scientist, I was able to write an algorithm to detect REM sleep from the raw EEG data.

Thirteen blinks can be seen in the minute featured above. They look uncannily similar to the rapid eye movements previously recorded with the halograph FM. The audio track was triggered five times throughout the night and interrupted REM sleep at least once.

Also of interest is that the attention graph tends to spike during REM sleep, when the meditation graph tends to trough.

Rapid Eye Movement Sleep
The audio tracks played three times during the night but ended the dreams each time. I woke up feeling very refreshed with the third song playing. Well over a dozen rapid eye movements can be seen in the featured minute.

Rapid Eye Movement Chart Blinks
14 blinks can be seen in the minute featured above. This is right before the audio track played in the next minute and ended the dream, rather abruptly.

2012-04-27 – Fast Beat

Rapid Eye Movement Graph Heartbeat
The blinks were too weak to activate the audio track, but the heartbeat reading is very clear throughout the entire recording. 16 REM blinks can be seen in the featured minute along with 74 heartbeats – much faster than usual.

The audio track played seven minutes into the dream and abruptly ended the rapid eye movements.

Preparation: smoked and chewed a few Calea leaves.

Rapid Eye Movement Dream

Six blinks can be seen before the audio track played, but I couldn’t contain myself and woke up. The latest version of Lucid Scribe now shows which track was played and makes navigating to the detected REM periods easier.

2012-03-20 – Eye Movement Types

Rapid Eye Movement Types
There are two distinct classes of eye movements that I have been observing. There are the solid blinks, five of which can be seen in the first twenty seconds of the minute above, that peak for over a thousand milliseconds.

Then there are the twitches, six of which can be seen in the second half, that barely last a hundred milliseconds. I suspect that some are lost because the resolution (10 FPS) is too low; there was probably one before and one after the four twitches in the middle.

REM during a Dream.
The track played within a minute of the onset of REM – after 8 blinks, and the dream lasted for almost 3 minutes, although the effect of the anthem is not noticeable on the eye movements.

2012-03-03 – REM Wave

Alternating Rapid Eye Movements
I can sometimes see a 30 second wave-like pattern in the intensity of the blinks; two such waves can be seen in the featured minute.

Alternating Rapid Eye Movements
The nine peaks in the minute above are part of seven phases of REM that occured during a ten minute window where the blinking started and stopped roughly every thirty to sixty seconds. The track had played twenty minutes earlier, but I have no memory of it.
